scroll within an uipannel that has multiple checboxes

Hello, I'm trying to create a fixed figure that may have multiple check boxes within it. I've created a pannel to aggregate all the check boxes. These check boxes are dependent on the data user is loading into the GUI - so these variables are not fixed. The problem is that when I have lots of variables, user cannot see all of them displayed. I think that the best solution is to use a scroll bar, but I dont know how to build its callback. Attached you can see a piece of code with my problem. Can anyone help me? Best regards, Susana

Best option is probably to search on file exchange for scrolling panels. I'm pretty sure there are numerous examples there. I wrote my own based on some logic I saw somewhere I forget now because I rarely like 3rd party code for something I want to extend with my own functionality, but if you just want a basic scrolling panel you should be able to get a ready working one off file exchange.
